Description

Simple and easy fixed porous track inhales salivary duct

Technical Field

The utility model belongs to the technical field of medical instrument, a inhale salivary duct is related to, especially relate to a simple and easy fixed porous track inhales salivary duct.

Background

The saliva suction technology is a technology for sucking and removing water mist, debris, blood and saliva in the oral cavity by using a saliva suction device in the oral cavity outpatient treatment process so as to keep clear operation visual field and assist the smooth operation. This technology is used throughout the various fields of oral treatment, and is the most basic nursing practice skill in the oral clinic.

The purpose of saliva absorption is:

(1) keep the oral operation field clear and reduce air pollution. During the operation process, the proper amount of water sprayed by the mobile phone and the tooth cleaner is cooled and washed, a large amount of water is easy to accumulate in the mouth, the operation part is shielded, water mist is splashed, the operation is not facilitated for a doctor, when the preparation and the polishing and the jaw adjustment of the tooth body are carried out, no fragments exist in the mouth, a large amount of water mist smoke and aerosol are generated, and air pollution is easily caused.

(2) Reduce the choking risk of the patient and improve the treatment comfort of the patient. In the treatment operation process, saliva or bleeding is continuously secreted by the oral cavity of a patient, and in addition, water mist sprayed by a mobile phone or a tooth cleaner accumulates in the oral cavity, so that the patient easily suffers from nausea, chocking and mistaken swallowing, the gargling frequency of the patient is increased, the operation efficiency of a doctor is influenced, and the comfort level of the patient in visiting is reduced.

(3) Ensure the effective moisture insulation of the treatment area and improve the efficiency and quality of treatment. In the operation processes of tooth filling, root canal therapy and the like, strict moisture insulation is required, and the saliva absorption can avoid the influence on the bonding performance of some materials due to poor moisture insulation, so that the treatment effect is influenced.

(4) Effectively assist in drawing the mouth and the horn, protect the tongue body, reduce iatrogenic injuries and ensure safer and smoother treatment operation. During operation, the assistant can assist a doctor to draw the mouth angle while sucking saliva, so that the operation area is more fully exposed, soft tissues of the part of the oral cavity of the patient, which is easy to be accidentally injured, can be protected, the tongue body can be blocked, and the tongue body and the tongue abdomen of the patient can be protected from being injured.

In the process of oral outpatient treatment, if a doctor operates the lower jaw posterior dental area or a patient with a large tongue body, a nurse is needed to assist in protecting the tongue or buccal mucosa of the patient from being damaged by a mobile phone car needle, and the tongue body or the lips are pulled to reserve enough operation space for the doctor. At this time, the simple saliva suction tube is difficult to resist the linguality force which is resisted by the instinct because the tube body is not stable in shaping, and the oral cavity which is not big originally is narrower if a nurse reuses other instruments.

CN209032693U discloses a saliva suction tube for oral cavity, which comprises a suction head, a drain tube, a steel wire, a saliva suction tube clamp, a filter screen and a connecting tube; the front end of the liquid discharge pipe is provided with a suction head in a matching way, the rear end of the liquid discharge pipe is provided with a connecting pipe in a matching way, the wall of the liquid discharge pipe is provided with a saliva suction pipe clamp in a matching way, and the saliva suction pipe clamp is provided with a mouth angle drag hook; a steel wire is arranged in the pipe wall of the liquid discharge pipe, and a filter screen is arranged in a pipe cavity at the tail end of the liquid discharge pipe; the drain pipe is of a conical structure, the caliber of the head of the drain pipe is 3-4 mm, and the caliber of the tail of the drain pipe is 6-7 mm.

CN106963508A discloses inhale salivary duct mechanism, inhale salivary duct mechanism and include first pipeline, second pipeline and third pipeline, and first pipeline cup joints on third pipeline surface, and the second pipeline cup joints on first pipeline surface, the surface of first pipeline still articulates there is the baffle, be provided with the branch that sets up along vertical direction on the second pipeline, branch one end is fixed second pipeline surface, the other end with the lower surface of baffle contacts, the one end of third pipeline is enclosed construction, and the other end intercommunication has the hose, keep away from in the third pipeline the circumference side of the one end of hose is provided with a plurality of rectangular shapes and runs through the groove.

CN204562436U discloses a saliva suction tube with a tongue stopper, which comprises a saliva suction tube and a detachable tongue stopper; wherein, inhale the salivary duct and constitute by straw, suction head and metal shaping silk: the metal wire is fixed on the inner wall of the suction pipe, the top of the suction pipe is a suction head, and the suction head is provided with a grid hole; the tongue keeps off for oval separation blade, and the parallel distribution has two tongue to keep off the design silk in the tongue keeps off the body, and the internal surface that the tongue kept off has the protruding muscle of friction, prevents that the tongue keeps off rotatory after the atress, and tongue keeps off the middle part and still opens the jack, and the suction head one side at the straw is adorned through the jack cover to by the go-between fixed connection of cover at the straw. When the utility model is used, the tongue block can be selected and installed according to the tooth position and the tongue body size of the patient; the radian of the tongue block is adjusted in the drawing direction.

The steps are complicated during oral operation, the postures are changeable, the vision of doctors is easily blocked by the saliva sucking hands of the assistant in the four-hand operation process, and the postures and the saliva sucking positions of the two hands need to be continuously adjusted to obtain a better vision. The form of the saliva suction tube needs to be adjusted repeatedly in the process of transformation, irregular deformation is easy to cause, when the mouth angle is pulled or the tongue body is blocked, the force is insufficient, rebounding and resetting are easy to occur, and the effect is not good; when the doctor does not use four hands to operate, the doctor needs to directly bend the saliva suction tube and hang the saliva suction tube on the mouth corner, at the moment, the patient needs to stretch the mouth for a long time and bear the hanging of the saliva suction tube in an irregular bending state for a long time, the mouth corner is easy to cause injury, and even iatrogenic ulcer is generated after the operation.
